Little Snitch 2020 Mac powerful and versatile application that enables you to monitor the network traffic and intercept unwanted connection attempts.
Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.
Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.
Filter connections and monitor your network traffic with ease
The Little Snitch Network Monitor utility features a well-designed interface and provide easy-to-read animated and informative diagrams created based on real time traffic information. Hence, you can analyze bandwidth, connectivity status, traffic totals, detailed traffic history for the past hour and more.
You can filter the displayed data based on the process name or server port and group them according to your needs. Little Snitch helps you view traffic peaks, check the average bandwidth and save snapshots for further analysis.
Enable the Silent Mode for a distraction free working environment
The network traffic can be easily captured in the PCAP format while the network activity is displayed along various system events in order to provide a context. There is also a Silent Mode that allows you to get on with your work without being interrupted by any network related notifications. However, you can review the Silent Mode Log to create rules for connection attempts that took place during this period.
On top of that, you can group your rules in different profiles and enable them only when a particular profile is active. Thanks to Little Snitch’s status bar menu, you can choose the desired profile with just a few mouse clicks.
Enjoy the versatility of the Automatic Profile Switching function
At the same time, you can take advantage of the Automatic Profile Switching feature and associate different networks with certain profiles. Once the network is detected, the associate profile is automatically enabled. For example, you can use a set of filters when you are at home and more restrictive ruleset when you access the web from an Internet Cafe.
What is more, Little Snitch features a flexible temporary rule system that offers a number of options for rules that are effective only for a limited period of time. Furthermore, Little Snitch automatically analyzes your ruleset and indicates the presence of overlapping, redundant or invalid rules that you might want to delete.
- The connection alert now offers a wider range of options for the lifetime of temporary rules, ranging from 1 minute up to 30 days.
- Updated Welcome Window in Little Snitch Configuration to reflect the new design of the connection alert.
- Little Snitch now ships with built-in Internet Access Policy information for further macOS system components.
- Improved selection of relevant information from Internet Access Policy in Network Monitor.
- After a fresh installation Little Snitch Configuration no longer shows factory rules in the “Last 24 Hours” section.
Improvements in the Connection Alert:
- Fixed an issue causing the Research Assistant to be shown without any visible content.
- Fixed an issue causing the “Accept Modifications” button not to work.
- Improved keyboard control of the connection alert window.
- Rules for connections that are established via a helper tool (“Some.app via Helper Tool”) are now created for the parent application. This prevents these rules to stop working when the the helper tool changes its path in the course of an update of the parent application. The only exception to this are Terminal programs, for which the previous behavior of creating rules tied to a particular command line tool remains.
Other Bug Fixes:
- Fixes a local privilege escalation issue (CVE-2020-13095). By exploiting this vulnerability, users logged in to the computer can gain root privileges, but they cannot circumvent System Integrity Protection. Details about this issue will be revealed later.
- Fixes an issue in the connection alert causing the user’s host/domain choice to be ignored under some rare circumstances.
